MACHINE FOR FORMING SHEET-METAL SKYLIGHT-BARS.-

SPECIFICATION forming part of Letters Patent No. 455,621, dated July 7, 1891.

Application filed February 9, 1891. Serial No. 380,810. (No model.)

Machines forlllaking SkylightBars, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in sheet-metal forming-machines formakingskylight-bars from sheet metal, and it is carried out as follows. reference being had to the accompanying drawings, wherein- Figures 1 and 2 represent a plan, Figs. 3 and 4 a side, and Figs. 5 and 6 represent a longitudinal section, of the improved machine. Fig. 7 represents an enlarged end View as seen from X in Fig. 4. Fig.8 represents a per spective view of the metal plate from which the skylight-bar is made. Fig. 9 represents an end view of the finished skylight-bar; and Figs. 10, 11, 12, 13, 14, 15, 16,17,18, and 19 represent cro'ss-sections, respectively, on the lines X X X X X X X X X,shown in Figs. 1 and 2.

Similar letters refer to similar parts where ever they occur on the different parts of the drawings.

A A represent the sides or frames of the machine, which are secured together at a proper distance apart by means of stays or bolts 0, a a, as shown. In recesses or cut-away portions a a in the frames A A are located vertically-adjustable bearings B B, preferably provided with suitable adjusting-screws b b, by means of which the rollers journaled in said bearings are adjusted to and from each other according to the thickness of the sheet metal that is to be shaped between such rollers.

C c, D (Z, E e, F f, G g, ll 71, I i, K 70, L Z, and M m represent a series of rotary shapingrollers arranged in pairs and journaled in the bearings B B, each such pair of rollers being arranged at a proper distance from the next pair in the series to allow forthe proper shaping of the sheet metal as it is being fed forward between such sets of shaping-rollers.

N N are stationary supports arranged between each successive pair of rollers for the purpose of supporting the sheet metal as it is beingv fed from one set of rollers to the next one in the series during the shapingoperation.

o in Fig. 8 represents the sheet-metal plate from which the skylight-bar is to be made, and O in Fig. 9 represents the finished skylight-bar as it is delivered from the machine after being shaped and formed between the series of rollers above mentioned.

In practice I prefer to arrange in front of the first pair of rollers O c a pair of cylindrical rotary feed-rollers P 1), between which the sheet metal is introduced before being passed between the series of shaping-rollers above mentioned; but such feed-rollers may be dispensed with without departing from the essence of my invention.

P in Figs. 1, 3, and 5 is a work-support or table in front of the rollers P 1), upon which the sheet metal is laid and, guided to and between the feed and shaping rollers. said table being preferably provided with a rib or ledge p, against which one side of the sheet is being held as it is being introduced betweenthe rollers. Such rib may be made laterally adjustable upon the table P, so as to compen-v sate for variations in the width of the metal sheets that are to be shaped.

Q in Fig. 1 represents the driving-shaft journaled in bearings in the frames A A, which shaft is set in a rotary motion, preferably by means of belt-power applied to a pulley g thereon.

g is a loose pulley on the shaft Q, as usual.

- Each pair of rollers in the series is made male and female and the successive pairs of rollers are shaped so as to bend, crease, and shape the metal sheet passed between them until the sky1ight-bar O is produced, as shown in Fig. 9.

By reference to Fig. 0 it will be observed that the skylight-bar comprises a triangularshaped body 0 a longitudinal rib O depending from the lower side of the triangularshaped body and comprising parallel walls that terminate in divergent edge flanges 0 while the uppermost side of the triangularshaped body is formed with alongitudinal ribsection 0, which likewise comprises parallel walls that lie against each other.

For the purpose of completing the upper rib-section O, I employin connection with the series of shaping rollers hereinbefore described a 'pair of rotary rollers R which folconstruction, and operation of my invention, 2 5 low the last set of shaping-rollers M m and are I Wish to secure by LettersPatent and claimarranged on vertical supports to revolve in a Ina machine for manufacturing sheet-metal horizontal plane.
